Originally home to the Davizzi, a wealthy family of merchants and bankers, this fourteenth-century palazzo and its impressive façade look out over the adjacent piazza, once populated by medieval case-torri (tower houses). palazzo Davanzati is in fact an amalgamation of these case-torri and other properties belonging to the Davizzi, though it takes its name from another family, the Davanzati, who purchased the building in the late sixteenth century.
